Testing Labs
Explosion Proof Test Laboratories
International standards require electrical and non -electrical equipment installed in hazardous areas to prove it can withstand particular external events such as explosions, spark ignition, extreme heat and high impacts. To test these capabilities, you need special laboratories that can simulate such extreme conditions. KEMA Labs offers a wide range of testing services for electrical […]
Operation Optimization
Grid code compliance
As the power system decarbonizes, balancing services will have to evolve as well, starting with frequency and voltage control. Every power plant must prove its compliance to the grid code requirements, running specific tests when it is commissioned and upgraded and on a regular basis thereafter. With our deep experience of grid code requirements and […]
Ispezione di prodotto, certificazione e formazione
Certificazione di prodotto e servizi di ispezione
La crescente domanda di energia elettrica richiede alle utility di disporre di solide reti di trasmissione e distribuzione, sia per garantirne l’affidabilità che per ridurne i costi operativi. Le utility devono quindi accertarsi che le loro apparecchiature elettriche siano robuste e affidabili. Kema Labs 1  offre servizi di valutazione della conformità ben supportati dalle sinergie […]

On the way to compare the polarity reversal withstand capability of HVDC mass-impregnated and extruded cable systems
​The reversal of voltage polarity is essential in HVDC cablesystems with Current Source Converters (CSC), since it enables to revert the direction of the power flow. Mass Impregnated Non -Draining (MIND) cables are known tobe able to withstand the voltage polarity reversal without particular problems. TERNA, the Italian Transmission System Operator (TSO), has introduced since […]
